Illinois LLC Annual Report: Due Date, Fee, and Filing Rules
This article is provided for general informational and educational purposes only. It is not legal advice, does not create an attorney-client relationship, and should not be relied upon as a substitute for consultation with a qualified attorney or tax professional. Business formation requirements vary by state, and you should verify the laws that apply to your business before making legal or tax decisions.
Find your Illinois LLC annual-report deadline, check online eligibility, and gather the right information before filing to avoid preventable fees and delays.
Key Takeaways
Calculate the filing deadline from the LLC's anniversary month.
Check current online eligibility before beginning.
Keep a recurring reminder and retain accepted filing evidence.
An Illinois LLC must generally file an annual report with the Illinois Secretary of State before the first day of its anniversary month. The standard filing fee is $75.
The deadline is based on the company’s anniversary month—not the exact day the LLC was formed.
Before filing, check the company’s current Secretary of State record and the current annual-report instructions. The LLC’s status, management structure, and any changes you want to make can affect whether the ordinary online filing route is available.
When Is an Illinois LLC Annual Report Due?
An Illinois LLC’s anniversary month is generally the month in which the company was organized or admitted to transact business in Illinois.
The annual report is due before the first day of that anniversary month.
For example, an LLC with a September anniversary month should file by August 31 rather than waiting until September 30.
Anniversary Month | File No Later Than |
|---|---|
January | December 31 of the preceding year |
February | January 31 |
March | February 28, or February 29 in a leap year |
April | March 31 |
May | April 30 |
June | May 31 |
July | June 30 |
August | July 31 |
September | August 31 |
October | September 30 |
November | October 31 |
December | November 30 |

A company organized on September 15, 2026, for example, should plan for its first annual report before September 1, 2027, subject to the deadline reflected in its Secretary of State record.
Do not rely solely on a registered agent, formation service, or accountant to remind you. Put the deadline in the company’s own compliance calendar.
The Deadline Is Not the Anniversary Day
A common mistake is assuming the annual report is due on the anniversary of the exact formation date.
It is not.
If an LLC was organized on September 15, the relevant deadline is tied to the September anniversary month, not September 15.
The report should therefore be filed before September begins.
The same principle applies regardless of whether the company was formed near the beginning or end of its anniversary month.
How Much Does the Illinois LLC Annual Report Cost?
The standard Illinois LLC annual-report filing fee is $75.
The total amount payable may differ in certain circumstances, including where:
- The company has outstanding penalties.
- Prior amounts remain unpaid.
- Series-related charges apply.
- A payment-processing charge applies to the selected filing method.
Review the amount associated with the company’s actual Secretary of State record rather than assuming every filing will cost exactly $75.
Can You File the Illinois LLC Annual Report Online?
Many Illinois LLCs can file their annual reports electronically, but online filing is not available in every situation.
Review the current Illinois Secretary of State eligibility requirements before starting.
Situation | What to Do |
|---|---|
Active LLC with a standard report and no listed restriction | Follow the Secretary of State’s online annual-report procedure |
Administratively dissolved or revoked entity | Address reinstatement; ordinary online annual-report filing is unavailable |
More than eight managers | Use the alternative filing route confirmed by the Secretary of State |
Changing name, duration, purpose, registered agent, or registered office | Determine which separate filing is required |
Filing involves a power of attorney, multiple/layered signatures, or another listed exception | Confirm the appropriate submission method with the Secretary of State |
Active LLC with a standard report and no listed restriction

Administratively dissolved or revoked entity
Address reinstatement; ordinary online annual-report filing is unavailable
More than eight managers

Changing name, duration, purpose, registered agent, or registered office

Confirm the appropriate submission method with the Secretary of State
The published online eligibility restriction concerning the number of persons listed relates to managers, rather than simply the total number of owners.
Because Secretary of State materials can contain terminology relevant to different entity types, use the instructions specifically applicable to LLCs when preparing the filing.
Use Form LLC-50.1 to Prepare
Illinois uses Form LLC-50.1, Limited Liability Company Annual Report, for the LLC annual-report process.
Even if you intend to file electronically, reviewing the form beforehand can help identify the information you will need.
Start by confirming the LLC’s:
- Illinois file number
- Exact legal name
- Principal-office information
- Manager or member information, as applicable
- Business addresses for the required persons
- Registered-agent and registered-office information
- Authorized signer’s information
Compare the legal name and file number against the Secretary of State’s current company record rather than relying on an old invoice or third-party service account.
Treat this as a preparation checklist rather than a representation of the exact order in which questions will appear in the current online system.
If the electronic form differs from an old screenshot or guide, follow the current Secretary of State instructions.
What Information Can You Change on the Annual Report?
Do not assume the annual report can be used to change every piece of information associated with the LLC.
Some information can be updated through the annual-report process, while other changes require separate filings.
In particular, changes involving matters such as the LLC’s:
- Legal name
- Duration
- Purpose
- Registered agent
- Registered office
may require a separate Secretary of State filing rather than simply being entered as an annual-report update.
Identify the change first and then determine the appropriate filing.
Do Not Hide a Registered-Office Change in the Annual Report
The registered office has a specific legal function because it is associated with the LLC’s registered agent and receipt of official documents.
If the registered agent or registered office needs to change, use the applicable Illinois registered-agent/registered-office change procedure.
Do not assume entering a different address somewhere in an annual report properly completes that change.
This distinction is especially important when the company’s principal office has moved but the registered office has not—or vice versa.
What Happens If the Annual Report Is Late?
Missing the annual-report deadline can result in additional charges and eventually affect the LLC’s state status.
Illinois Secretary of State guidance provides for a $100 late-filing penalty when an LLC annual report is more than 60 days delinquent.
That does not mean the LLC has an additional 60-day filing period.
The report becomes delinquent after the actual annual-report deadline. The 60-day period relates to the additional late-filing consequence, not an extension of the original due date.
If the deadline has already passed, check the company’s current status and balance promptly.
Do not assume paying the ordinary $75 annual-report fee by itself will necessarily resolve the account.
Administrative Dissolution
Continued failure to satisfy annual-report requirements can have more serious consequences than a late fee.
An Illinois LLC that falls sufficiently out of compliance may face administrative dissolution. A foreign LLC may face revocation of its authority to transact business in Illinois.
Once that happens, the ordinary annual-report filing process may no longer be sufficient.
The company may need to use the applicable reinstatement process, submit delinquent reports, and pay the amounts required to restore its status.
Checking the company record early can prevent a relatively simple annual-report problem from becoming a larger reinstatement project.
Common Illinois Annual Report Mistakes
Before submitting, check for these common errors.
Wrong File Number
Compare the file number with the official company record.
Do not rely solely on an old provider invoice, email, or internal spreadsheet.
Wrong Filing Route
An administratively dissolved company or an LLC subject to an online-filing exception may need a different procedure.
Check eligibility before entering information or paying fees.
Incorrect Registered-Agent Changes
Do not attempt to make a registered-agent or registered-office change through an inappropriate annual-report field.
Use the separate procedure required by the Secretary of State.
Incomplete Management Information
Collect the required names and business addresses before beginning the filing.
This is particularly important for LLCs with several managers.
Ignoring an Existing Balance
A company with previous penalties or unpaid amounts may owe more than the standard $75 annual-report fee.
Review the account before submitting payment.
Assuming Payment Means Filing Was Accepted
A credit-card charge or payment receipt alone is not the best evidence that the compliance filing was completed successfully.
Retain the filing confirmation and a copy of the accepted annual report.
What to Do After Filing
Once the annual report has been accepted:
- Save the acceptance confirmation.
- Retain a copy of the filed annual report.
- Verify the company’s state record where appropriate.
- Record the next annual-report deadline.
- Confirm that the registered-agent information remains accurate.
- Update the company’s compliance calendar.
Keep these documents with the LLC’s permanent state records.
Build a Simple Annual Compliance System
Annual-report compliance should not depend on one email reminder.
Maintain a basic record containing:
- Illinois file number
- Exact legal company name
- Anniversary month
- Annual-report deadline
- Registered-agent information
- Current managers
- Copies of previous annual reports
- Filing receipts and confirmations
- Next filing deadline
Assign one person responsibility for the filing and another person as a backup where practical.
Set reminders well before the actual deadline rather than on the final filing date.
Illinois LLC Annual Report Checklist
Before filing, confirm that:
- The correct Illinois LLC record has been located.
- The company’s anniversary month is known.
- The filing deadline has been calculated correctly.
- The LLC is eligible for the selected filing method.
- The file number and legal name are correct.
- Principal-office information is current.
- Required manager or member information has been collected.
- Registered-agent information has been reviewed.

- Existing penalties or balances have been checked.
- The correct filing fee is being paid.
- The filing confirmation will be retained after submission.
Conclusion
The Illinois LLC annual-report deadline is based on the company’s anniversary month, not the anniversary day.
The report is generally due before the first day of that month. For example, an LLC with a September anniversary month should plan to file no later than August 31.
The standard filing fee is $75, although penalties, series-related charges, or other amounts can increase the total.
Before filing, check the company’s current Secretary of State record, confirm online eligibility, collect the required information, and identify any changes that require separate filings.
After acceptance, save the annual report and confirmation and immediately calendar the next deadline. A simple compliance system can help prevent late penalties and the more complicated reinstatement process that may follow administrative dissolution.
